MOTOR-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 706,978, dated August 12, 190

Application filed September 25, 1901. Serial No. 76,500. (No model.)

To all whom it may concern:

Be it known that I, HARRY J. MARKS, a citizen of the United States,residing at New York, State of New York, have invented certain new and useful Improvements in Motor-Vehicles, of which the following is a clear, full, and ex act description.

My invention relates to an improvement in motor-vehicles; and one of my objects is to provide a construction by which the motor is hung from the vehicle on a pivot, at one side of the center of gravity thereof, and is springsupported, whereby it may vibrate on said pivot when the vehicle passes over inequalities in the road, by which the motor is re lieved of sudden shocks.

Another object of my invention is to provide an improved driving construction.

My invention will be defined in the claims. In the drawings showing the preferred embodiment of my invention, Figure 1 shows a plan view, and Fig.5.. a sectional View on line oamof Fig. 1. n i v In automobile-vehiclesthe motor is usually heavy, and if it is rigidly supported on the vehicle the jars and concussions which it receives from the vehicle passing overinequalities in the road often injure it or strip some of the gears or loosen it from its support and cause the gears to chatter. I avoid these objections in the preferred construction. herein described by hanging the motor on a transverse pivot at one side of its center of gravity and also supporting it on a spring connection to the frame, so that the motor may vibrate back and forth on said pivot, and the jars which otherwise would be communicated to the motor will be taken up to a large extent by the spring. I prefer to have the axle upon which the driven vehicle-carrying wheels are mounted integral--that is, continuous throughout its length-instead of divided, for such an integral axle results in a much stronger construction than one in which the axle is divided.

In motor-vehicles it is desirable that both drivencarrying-wheels should not be driven at the same speed when the vehicle rounds a corner, as the inside wheel would skid, and if compensating mechanism is used to automatically drive the outside wheel while allowing the inside wheel to revolve slowly or not at all the driven axle could be divided into two parts which can be independently rotated. This is a weak construction. In my invention, however, I have provided a construction by which the axle upon which the vehicle-carrying wheels are mounted may be integral and yet in which such a compensating mechanism is interposed between the motor and the carrying-wheels to drive the same independently, as stated above.

In the preferred embodiment of my invention herein disclosed, 1 2 are longitudinal runners forming part of the frame of the vehicle. The axle3, preferably the rear one, is mounted in the frame and is preferably integral-that is, continuous throughout its length. The vehicle-carrying wheels 4 5 are mounted on the ends of the axle. I prefer to have the axle fixed to the framethat is, not rotatable therein--and to allow both said 'wheels to rotate freely thereon. 6 and 7 are gear-wheels fixed to the said carrying-wheels.

8 9 represent the source of power or motor, in the embodiment illustrated consisting of a pair of steam-engines whose piston-rods 10 and 11 are connected to the cranks of a driven shaft 12.

13 is a driving-wheel keyed to shaft 12, preferably having gear-teeth cut thereon.

The engines are hung on the vehicle on a pivot transverse of-that is, not perpendicular toand preferably parallel to the wheelbase and at one side of the center of gravity therefrom as possible, so that the pivot will support only a small part of the weight of the motor. In theembodiment illustrated I turn trnnnions 14 15 on the engine-casing, which liein pillow-blocks on the runners l 2 (one of which pilloW-blocks'is shown at 16) and are held in place by removable caps, one of which is shown at 17. Similar trunnions rest in pillow-blocks in the portions 18 19 of the frame. The motor may be supported, preferably at the other side thereof, by springs 20 21, located above and below a cross-piece 22 of the vehicle-frame, so that motion of the motor either up or down is resisted by the springs. The driven shaft 12 is preferably concentric with and rotates in the trunnions. The driving-wheel-13 vibrates with the motor and is preferably, but not necessarily, also of the engines, preferably as far removed concentric with the pivot on which the engine is hung.

In order to transmit the motive power to the carrying-wheels, so that they may be driven substantially independently, I have in this embodiment provided a compensating mechanism having a pairof independentlyrotatable wheels, each of which is preferably mounted on an independent division of a shaftand connected to the carrying-wheels to drive the same independently. This compensating mechanism inth'is embodiment includes a gear-wheel 23, meshing with drivingwheel13 and fixed'to the gear-case 24:, which carries one or more bevel-gears 25, Fig. 2, each freely rotatable on a stud (not shown) fixed to the gear-case. Independently-rotatablebevel gear-wheels 2'6 and 27 mesh with the gears 25 and transmit motion to the carrying-wheels 4 and 5. I preferably key the gears'26 and 27 to the ends of independent divisions 28 29 of a shaft journaled in the frame, and these divisions may carry gears 30 31, which mesh with the gears 6 and 7. When the vehicle travels ina straight line, the bevel-gears 25 do not rotate on their studs, but are carried around with the gear-case and rotate both wheels 26 27 at the same time; but when one of the carrying wheels is held for instance, the inside wheel when the vehiclev rounds a curve-the, gears 25 rotate on their studs and drive the other carryingwheel faster.

The point of contact between drivingwheel 13 and wheel 23 will not change, no

matter how far the motor rocks on its pivot,

as the driving-wheel is in this embodiment concentric with that pivot, and in order to keep the center of wheel 23 at a fixed disof the train does not change no matter how far the motor rocks on its pivot, and this'keeps the .gears in mesh and tort great extent pro-- vents chattering of the gear,.which is very.

objectionable. r

I am aware that many changes may be made in the constructions heretofore illustrated and described without departing from the spirit of my invention, and I therefore do not limit -myself to the embodiments herein disclosed.
